That's innanswerable, take for instance rain, which comes in many different sizes, it's terminal velocity is reached when the force of friction becomes equal to the force gravity is applying on it. But as water groups together in different sizes and therefore when falling has different levels of friction it falls at different speeds and so the terminal velocity of water depends on the amount of water

∙ 10y agoA rain drop is accelerated by gravity at 21.9369 miles/hour per second but quickly reaches a terminal velocity of around 20 miles per hour (maximum speed) due primarily to air friction. Other factors include the size of the rain drop, rain fall density, wind speed and direction, pollution, pollen and dust particles and barometric pressure.

∙ 14y agoAs a raindrop falls, some of the water evaporates (depending on relative humidity) leaving less mass. The size and surface area would also decrease, but at a slower rate than the decrease in mass. This would leave a raindrop with a higher surface area to mass ratio. Since air resistance is related to surface area, the smaller raindrop will have more relative air resistance for it's mass and will fall more slowly. Another factor would be the increasing density of the atmosphere as the raindrop approaches the Earth, slowing the raindrop even more.

Does rain reach terminal velocity?
Yes
If a liquid is thick and you drop an object in to it is the terminal velocity larger or smaller?
Smaller.
What is the terminal velocity of a falling object on earth?
An object that has reached its terminal velocity is going at a constant velocity. Acceleration is the rate of change of the velocity. The rate of change is zero. Therefore, the acceleration is zero.
What is the reason for rain drops to fall with a constant speed by the time they reach earth?
They reach their terminal velocity.
What does a parachute do to terminal velocity?
It decreases the terminal velocity of the parachutist.
Which fall faster big rain drop or small rain drop?
The viscosity of air provides a drag force on a raindrop and keeps it from falling with the acceleration of gravity. When a drop is falling (assuming it does not combine with other drops in the process) it will reach a terminal velocity which depends on its diameter. The larger the diameter the larger the terminal velocity. Specifically, the terminal velocity is proportional to the square root of the diameter of the drop. Big rain drops fall faster than small rain drops. See related links for details and equations.
Does rain reach terminal velocity?
Yes
Why a larger rain drop falls faster than a small rain drop?
Considering the rain droplets as spherical body. We have two forces acting on the rain drop when it is falling through the sky, namely the resistance force due to friction(drag force)upwards and its weight downwards. Th rain drop falling from such distance attain a terminal velocity while falling i.e their speed becomes constant after sometime. This happens when the drag force equals the weight of drop,, this happens because drag force increases with velocity of the drop. Drag force= .5*rho*v2*A(frontal area)*Cd(coefficient of drag) Weight=m*g=rho*volume of spherical drop=rho*4/3*r3. When we equalize it, we get the Terminal Velocity(v) varying directly as sqr of r(radius of drop) So larger drop means, larger terminal velocity and hence less time taken for falling. So larger rain drop falls faster.
Clouds are very high in the sky but the rain-drops falling from the clouds havelow velocities as they reach the ground.?
the reason why is because of the shape and weight if the rain drop. the weight of a rain drop is less than a gram and the shape of one when falling from the sky, has a lot of drag. this means that the terminal velocity of a rain drop is very slow
If a liquid is thick and you drop an object in to it is the terminal velocity larger or smaller?
Smaller.
What is acceleration of a rain drop that falls at a constant velocity?
If the velocity is constant then there is no acceleration. The acceleration is zero.
What is the direction and magnitude of the net force acting on a rain drop falling down with constant speed?
If the raindrop is falling at a constant speed, then it has reached terminal velocity. This happens when the downward force (due to gravity) is the same as the upward force due to friction. As such the net force acting on the rain drop is 0.
What is the terminal velocity of a falling object on earth?
An object that has reached its terminal velocity is going at a constant velocity. Acceleration is the rate of change of the velocity. The rate of change is zero. Therefore, the acceleration is zero.

When gravitational forces and air resistance equalize on an object that is falling toward earth and the object stops accelerating its velocity is called?
In that case, the object is said to have achieved terminal speed.
What is the speed an on object reaches when the force of gravity is balanced by air resistance called?
terminal velocity
